Well-friction properties of ball bearings lubricated by tribo-coating of indium were maintained for one year exposure to real space field. Even after degradation of ball bearing due to exposure to the real space environment, friction properties could be restored by in-situ tribo-coating., Physical characteristics: Original contains color illustrations, 資料番号: AA0064307013, レポート番号: JAXA-SP-08-015E}, pages = {121--125}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {SM/SEED space exposure experiment of ball bearing lubricated by trobo-coating}, volume = {JAXA-SP-08-015E}, year = {2009} }
